Exchange and iSCSI
by Holland, William L 21 Mar '05

21 Mar '05

Is SnapDrive and SnapManager for Exchange really needed to run Exchange with databases on a filer using iSCSI? Seems to me that it would be possible to use MS's iSCSI initiator then manually create the iSCSI Groups and LUNs where the databases and logs will be stored then use scripts to perform routine maintenance and backups. Anyone out there using Exchange and iSCSI without SnapDrive and SnapManager for Exchange?

df size reporting differences in ONTAP 7.0
by Adam McDougall 19 Mar '05

19 Mar '05

This sunday I upgraded our production FAS940 from 6.5.3 to 7.0 and noticed NFS clients are reporting the user or group quota as the volume size and free space when running df, when 6.5.3 and earlier used to report the qtree quota. I was suprised by this change and so far have been told by NetApp that it is a bug fix, not a bug. Just wanted to send a heads up to the list to let people know, and wondering if anyone else was affected negatively by this. I like part of the idea of the change but was not expecting it at all. Didn't see it in docs. Its interesting but inappropriate for some of our volumes the way we have quotas setup, and it prevents non-admins from seeing if the volume or qtree is nearing full.

RE: Windows Shadow Copy Client & Snapshots

I don't know about that, I've only just become aware that it can be used and we're on version 7.0.0.1. And I know that I couldn't get it to work before switching on the snapshots using that command. Interestingly enough, and I've not got back to NetApp about this yet, I turned it off again - as I'm still not sure about providing this facility - and it still works. But it definately didn't before turning on that setting. Now that I've switched it off again I keep expecting the facility to disappear, I've been waiting to see what happens.

We are running 6.5.3P4 and have that option turned off and STILL users with Windows Shadow Copy Client can see the previous versions of their files and folders. We deliberately turned off showing the snapshots on CIFS because our users were confused about it (most of them have "show hidden files" option turned on). We installed the shadow copy client on their machines to help them do the restores themselves without the hassle of them "seeing" multiple copies of the same files when they do a search or browse through their shares and folders. The Shadow copy client was perfect for our needs - no ~snapshot folders visible, yet users can restore previous versions by themselves. NOTE: Even with show_snapshot set to off in 6.5.3, one can go into the snapshot folders by manually typing in the path, e.g: \\<filername>\<share_name>\<dir_name>\~snapshot\ either in the Run command box or widnows explorer. This would show the traditional snapshot folders. One more reason for us to stay away from 7.0.0.1 for now. Hope NetApp reverts the behaviour back to how it was in 6.5 and earlier versions.

RE: Requests on Slashdot for donations for OpenBSD.
by Hitz, Dave 16 Mar '05

Although NetApp's OS looks nothing like BSD (it has no user space for instance, and a very different internal structure from any UNIX kernel), we certainly did use a good bit of code from the Net/2 and BSD-lite releases, back when that was being mostly funded by Berkeley and DARPA. As Luke says, we used the TCP/IP stack. Also the boot and locore code for both Intel and Alpha. And although we don't have a user space for commands to run in, we did take chunks of user space code in commands like "ping" and "ifconfig" and massage them into kernel code. I don't know the specifics, but I'd be surprised if we hadn't found more stuff to borrow over the years. I confess that we haven't made any dollar contributions, although if you look at the code contributions I think you'll find that Guy Harris (also of NetApp) and myself were both early contributors. For instance, I contributed cp(1). (When I was done, "cp -R" was a good bit faster than the AT&T version. Instead of doing the copy for a directory in a single pass, I scanned the directory twice, doing files on the first pass and directories on the second. This optimized for the fact that in FFS files in a directory tend to end up in the same cylindar group, so doing the files all together reduces disk seeks.) So at the time, we figured that we gave some code, and took some code -- call it even-Steven. :-) Not that I would object if we found a way to make a corporate contribution. We have made some source contributions to Linux, and I've personally made some contributions to Mozilla, so we are definitely fans of the open source movement.

RE: Quotas

Actually that sounds very similar, at first this affected only a few Qtrees & Home folders on the two volumes. Toward the end of yesterday afternoon I thought the filer had sorted itself out, this morning it started again around 09:30Hrs and was affecting pretty much all our qtreees & home folders. The problem became apparent yesterday around 13:00Hrs and dropped off around 16:30Hrs, starting again around 09:30hrs this morning but worse! So there may be some correlation between filer workload and this problem. What DFM was reporting and initially alerted one of the guys to there being a problem, was that about a dozen Qtrees were, according to DFM, set at 50Mb. The quotas file had them set to 31.5Gb. When a asked the filer for a quota report it itially told me that the quotas were set to 50Mb as well, after a quota off followed by a quota on I again queried the filer for a quota report, this time it reported the quotas correctly BUT still users couldn't write to their Qtrees or Home folders. I even forced the cluster partner to take over the disks and rebooted the filer having the problem but that dind't resolve it either.

Well, it's alarmingly reminiscent of two recent toasters threads "unix quota and df" (Charles Bartels) "df size reporting differences in ONTAP 7.0" (Adam McDougall) except that they didn't actually report "disk full" conditions. I think the chances of us going to ONTAP 7.x at Easter are now almost indistinguishable from zero! Many thanks to those of you who jumped in the deep end, and let us know where to send the wreath ... :-) It's a pity that no-one from NetApp has contributed to any of these threads.

However, if it makes sense to use different NFS options for different applications, then I believe you can still do it. Just mount the same netapp volume on different mount points with different sets of NFS options, and on the NFS client have each app use the appropriate mount point for the NFS options it needs. mount -o rw,hard,opt2,opt3 toaster:/vol/big /mnt1 mount -o rw,hard,opt4,opt5 toaster:/vol/big /mnt2 ...

Hi - I have all our Oracle9i databases defined as individual qtrees spread over two filers. Some time ago the decision was to split an individual database into 3 separate components (qtrees), one for the data (tables) the other two qtrees for duplex logs, one on each filer head. A Sun Solaris 8 dataserver that runs 6 Oracle databases then has 18 nfs mounts. On the recommendation of NetApp the qtrees are mounted with these options: rw,hard,intr,bg,proto=tcp,llock The DBAs now would like to have this rearranged so that there is a single qtree per dataserver host (think of this as one large blob of space) with ALL of the databases that this server will run as a sub-directory of this qtree. I'm a bit worried over the resultant nfs performance all going though this single mount point. Can someone comment on the issues of multiple nfs mounts vs. a single mount ? What about locking ?

This is good; although this is *not* the way things worked pre-ONTAP 7.0 Ex. User1@unixbox> df -kh . Filesystem Size Used Available Use% Mounted on filer:/vol/vol0/home/user1 5.0G 2.0G 3.0G 40% /home/user1 If a user's home directory is in a volume, their "partition" shows up sized to the size of the volume. They need to run "quota -v" on the client to get their quota. Ex. User2@unixbox> df -kh . Filesystem Size Used Available Use% Mounted on filer:/vol/home/user2 32G 11G 21G 35% /home/user2 User2@unixbox> quota -v Disk quotas for user2 (uid 1001): Filesystem usage quota limit timeleft files quota limit timeleft /home/user2 1914808 5242880 5242880 2172 -1 -1

Full volume backup with Legato Networker
by Palmer, Jason (EMEA) 15 Mar '05

15 Mar '05

Hi - At present, we back up our F800 series filers with Legato Networker using NDMP and direct attached tape devices. We are looking to purchase an R200 and mirror our live data on a daily basis to this device in an offsite location and perform periodic backups to tape. We would like to backup the full volumes - the current file system plus all of the snapshots. I understand that a Dump commnd can be used to push the whole volume out to tape and a snapmirror to tape type scenario could also be used. Does anyone currently do this using their Legato backup software ? If so, could they give details of how this could be done ? I have heard that Netvault from Bakbone may have this type of functionality - anyone out there using this ?

RE: Multimode VIF
by Dean, Phil (ITO) 15 Mar '05

You need to take into account the port now. So a dual card has ports a and b so you do e4a and e4b to create the vif for all ports on card 4. if you had a quad port card then you have a, b, c and d as the ports so e4a to e4d.

Basically I have two of the new dual GB cards one in slot 4 and the other in slot five. I would like some ideas since I have only historically done single mode VIFS (1 port per card) like the following: vif create single trunk1 e4 e5 vif favor e4 ifconfig trunk1 x.x.x.x netmask 255.255.255.0 wins route add default x.x.x.x 1 What I want to do is a multimode using the 2 dual cards, each one going to separate switches (2 connections per card - per switch). Unfortunately from what I understand, the Cisco 6509 does not support Active Active trunk groups across 2 different switches. We can however have an active active trunk created between 2 ports on the same switch. So I would like to have 1 dual card go to one switch (On two different blades), and the send the other two to another switch. I would like 2 of the 4 ports transmitting/receiving under 1 virtual address. Essentially, most of the switch failures I have seen are logical, on the port or blade. In this event the netapp does not failover. My thoughts are if I go on 2 different blades on the same switch, and I have both cards transmitting, and receiving, then if I lose one port or blade, I will have another card. If we lose the whole switch,then we would failover to the secondary VIF. Do I create 2 different VIFS, and then create a 3rd VIF, (Essentially viffing the VIFS) I am sure I am not the first to head down this road, so any helpful advice would be great, I am not finding to much on the NOW site.
